Patent DE-3441580-A1 (DE)
Title: Work device or the like provided with attachment screws
Inventor: BERGER GUNTER
IPC: A46B7/04
Filed: 1984-11-14
Abstract: The subject-matter of the invention is the connection of work devices, such as tar scrubbers, to a handle holder by means of manually operable wing screws which are screwed directly into the brush body. Hitherto, handle holders have been mounted as follows:   1. by means of so-called carriage bolts in conjunction with wing nuts, 2. by means of wing screws with a metal thread in conjunction with countersunk special nuts,   3. by means of hexagon wood screws.   The progress of the present invention lies on the one hand in making the device less expensive by using wing screws which can readily be screwed directly into the body by hand without further tools and dispense with the use of further check nuts or screws. On the other hand, there are technical advantages, such as changing a used and therefore often gummed-up tar scrubber from the handle holder or from the handle for a new tar scrubber. In the conventional type, it is very difficult to release the wing nuts from the carriage bolts since, for example, the mass of tar gums up the thread of the carriage bolts. This difficulty does not occur in the present invention since the thread of the wing screw is located directly in the wood. <IMAGE>

Title: Wood pulping with acetic acid
Inventor: NIMZ HORST H PROF DR
IPC: D21C3/00
Filed: 1984-12-11
Abstract: In a process for producing cellulose pulp from wood or annual plants by percolation at 100-112 DEG C with aqueous acetic acid which contains 0.05-0.2% of hydrochloric acid at the start and 0.5-2% of hydrogen peroxide at the end, the pulp yields (40-60%) and kappa numbers (2-30) can be varied as desired with pulping times of between 2 and 5 hours. All softwoods and hardwoods and even pinewood can be pulped. The process is environmentally sound, because it requires neither sulphur-containing digestion chemicals nor chlorine-containing bleaches. Lignin and hemicelluloses can be readily separated from one another and are little changed.
Patent DE-3446443-A1 (DE)
Title: Barometer having a digital display
Inventor: SIEBERT HANS
IPC: G01W1/02
Filed: 1984-12-20
Abstract: On the barometer having a digital display, in order to display or to make visible at any time the respectively just occurring air-pressure change in addition to the instantaneous air pressure, an electronic measurement memory is provided in a control electronics device (1), which memory is driven by a mechanical or electronic reversing switch (3). The reversing switch (3) always switches when the air pressure starts to fall after a previous rise or starts to rise after a previous fall, so that a previously stored measurement in the measurement store is deleted and the instantaneous measurement is stored as the new pressure-change reversal value and, at the same time, is displayed in a separate, digital display device (5). The observer thus has the capability to determine at any time whether the instantaneous air pressure value is above or below the display pressure-change value, that is to say whether the air pressure is rising or falling. <IMAGE>

Title: Method for cleaning goods with an organic solvent
Inventor: ZOTT MANFRED
IPC: D06F43/00
Filed: 1985-06-29
Abstract: The invention relates to a method for cleaning goods with an organic solvent, in which a solvent liquor is continuously filtered in a circuit leading over the goods in a first treatment phase, then is circulated unfiltered during a further phase with an addition of water and cleaning enhancers and is finally filtered again in a third treatment phase which then follows, after which the liquor is drained. In order to increase the service life of the filter absorbing the soilings during this circulation, it is intended according to the invention that, after completion of the second treatment phase before the start of filtration, when the soil concentration in the liquor has reached a maximum, a part of the soiled liquor is removed from the circuit and replaced by fresh solvent (Figure 2). <IMAGE>
Patent DE-3526742-A1 (DE)
Title: Guide sleeve with a striker for driving (bone) chips in bone
Inventor: JANSSON VOLKMAR DIPL ING
IPC: A61B90/00
Filed: 1985-07-26
Abstract: For improved guidance and simpler driving of (bone) chips in bone during specific operations, a chip is inserted in a guide sleeve and knocked in by striking on the striker. At the same time, the guide sleeve and the striker can be movable relative to one another or can be fixed. The guide sleeve end facing the substrate can be designed such that slipping of the guide sleeve off the substrate is prevented (spikes, geometric fitting). The guide sleeve end facing the substrate can be widened in order to ensure better striking on the substrate; however, in restricted operation conditions it should have thin walls. The guide sleeve can be designed with slots in the longitudinal direction in order to achieve a better access to the chip. For determination of the driving depth a length mark can be made on the striker. In order to facilitate handling in restricted operation conditions the guide sleeve or the striker can also be curved. In order to prevent slipping of the guide sleeve off the pre-chiselled bone cleft it is possible to provide a rail on the guide sleeve which can be inserted in the gap and can thus prevent slipping.
